Can opener

Abstract

A pocket can opener comprises a body with a propelling wheel and a handle for rotating the propelling wheel and a cutter blade pivotally attached to the body so that both the handle and the cutter blade can fold down across the body with the cutter blade overlying and being of such a size as to cover the propelling wheel when the can opener is in inoperative condition. The cutter blade also provides a bottle opener at its free end having a longer arm and a shorter arm, the longer arm being shaped also as an opener for pressed-on jar lids, this latter opener structure being so arranged as to take up no additional space in the folded condition of the parts. Also, a further blade is pivoted on the first-mentioned blade and has sharpened edges for puncturing and slitting aluminum or plastic or other packaging materials for food products and is so constructed as to lie flat against and be masked by the longer arm of the bottle opener in its inoperative condition but to project freely and have purchase against a guide bar of the can opener in its operative condition, in which latter case the first-mentioned cutter blade becomes in effect part of a handle for the puncturing and slitting blade.

What is claimed is: 
     
       1. In a pocket can opener comprising a body with a propelling wheel and a handle for rotating the propelling wheel and a cutter blade pivotally attached to the body so that both the handle and the cutter blade can fold down across the body with the cutter blade overlying and being of such size as to cover the propelling wheel when the can opener is in inoperative condition; the improvement comprising a second blade pivotally mounted on the same pivot as the first blade and on the side of the first blade opposite the body, said second blade having a pair of legs whose confronting surfaces are sharpened edges for slitting flexible packaging material. 
     
     
       2. An opener as claimed in claim 1, and a tongue on said second blade that contacts said first blade in the inoperative condition of the second blade to maintain the second blade in a position in which said second blade is masked by said first blade. 
     
     
       3. An opener as claimed in claim 1, said first blade being pivotally mounted on said body adjacent one end of said first blade and having a bottle opener at the other end of said first blade, said bottle opener having a longer arm for engaging the tops of bottle caps and a shorter arm for engaging under the rims of bottle caps, and means positioning said second blade in an inoperative position relative to said first blade in which said second blade overlies and is masked by said longer arm. 
     
     
       4. An opener as claimed in claim 1, said body having a guide bar that overlies and rests on the rim of a can during a can opening operation, said second blade engaging said guide bar in an extended position of said second blade whereby said guide bar limits rotation of said second blade about said pivot. 
     
     
       5. An opener as claimed in claim 4, said first blade having a cutting edge thereon for opening cans, said cutting edge being masked by said body and by said second blade and by said guide bar when said first blade is folded against said body and said second blade is in contact with said guide bar.
